Youth Bamboo Rayon Socks size 4

Here's the thing about bamboo:

100% Bamboo (or for socks, 94% Bamboo rayon and 6% Spandex). 

• They're soft, soft, soft!
• Rumor has it that bamboo rayon fibers are both highly absorbent and possibly bacteria resistant. What better qualities are there for a sock, we ask.
• Bamboo itself is a very renewable resource that grows fast without chemicals and pesticides
• They are 94% pure Bamboo rayon that has been developed in the same way other Rayon fiber is, but made from bamboo, and 6% Spandex for stretch. Possible pilling when put in the washing machine with rough textured fabrics
